Harris turns 60: How her age compares to past presidents

• Age took on an outsized role in the 2024 race when Biden was on the ticket, as many voters felt he was too old to be president.
• More recently, Trump's age and acuity have been under scrutiny.

By the numbers: Trump and Biden have bent the presidential age curve upward (see chart). Just 12 presidents have taken office in their 60s or 70s.

• Prior to Trump, Ronald Reagan (69) was the oldest president elected for the first time. He was 77 when he left office after two terms, still a year younger than Trump is now.
• The youngest presidents upon taking office were Teddy Roosevelt (42) and John F. Kennedy (43). Since Kennedy, the youngest were Barack Obama (47) and Bill Clinton (46).
• Jimmy Carter, meanwhile, is the longest-lived president ever, at 100. He cast a mail-in ballot for Harris on Wednesday.

Editor's note: This story has been corrected to say that Teddy Roosevelt took office at age 42 when William McKinley was assassinated, not that he was elected at age 42.
